Each entry represents an active SDP binding loopback. The SDP binding is placed in loopback by row creation and is removed by row destruction. Rows in table sdpBindEthLoopbackTable are created and destroyed by SNMP set operations on the object sdpBindEthLoopbackRowStatus. Rows in table sdpBindEthLoopbackTable may be destroyed by the system when the associated SDP binding has been deleted. A maximum of 64 rows may be created. Rows are kept in volatile storage and lost upon a system reboot.
